Hi besides.
That is absolutely false, as far as general knowledge in this subject goes.
The closest that rumors have ever gone to that was when news came out that the only PES6 next-gen version that Konami would be making would be for the XBox360. Why is that, you ask? Because there was no install base for making it to any other next-gen platform at the time (and, unless I am completely forgotten, I believe that the PS3 wasn't even out when PES6 came out for the 360...?).
Nonetheless, those were the reasons for that. The thing from then on is purely semanthics: news sites started hyping all over "PES next-gen will be exclusive to Microsoft for one year" (which later on they corrected, and said they meant "PES next-gen will be exclusive to Microsoft in 2006"). This was not big news at all - just a simple fact that could be observed, and then hyped in news sites to create buzz about PES6 on XBox360.
About Microsoft buying Konami...? No way it will happen for now at least

They are much more interested in acquiring Yahoo for their online advertising, to compete with Google-ads... Remember that the Games division in Microsoft is not profitable for them yet.
Well, enough about this, back on topic then

Great info you guys got here, I've been following this thread closely and will keep it up.
The only thing I can actually contribute to it is that there is one tiny detail that can help us have a bit of more hope in what concerns the need for a patch for the menus:
Correct me if I'm wrong, but I believe that there was one past release of Winning Eleven (excluding the "WE7 International" and all the other "Final Evolution"s) that had their menus already in English... Only the menus, though, nothing else - names and commentary in Japanese. I believe it was Winning Eleven 9 - the one with the Nippon Challenge... I can't confirm, though, and I'm not sure if it was only the main menu or the sub-menus too... I might be delusional, too
Hopefully we'll have more news about this in the near future - May 18th (wishful thinking?

).
Best regards, and keep up the good work guys.
